We have all seen them on the TV news, a crime committed on camera, but the analog camera resolution is so poor the police can't identify the perpetrator and are hoping some member of the public can help. Analog cameras have their place, at least as intimidation, so the signs saying "Premises under Video Surveillance" are not inaccurate.

But as for audio and TV, digital is the path to better performance and more capability in security imaging. The analog to digital (A/D) conversion is done inside the camera close to the CCD/CMOS imaging sensor, retaining the most quality and least noise. The image then is transmitted digitally making it highly tolerant of noisy environments. Since the A/D conversion is done in the camera it does not suffer the distortion that tens of meters of cable or the electrically noisy computer can inject to distort the analog image. This all increases the capabilities of the security system.

So what are the improvements when a digital surveillance system is used? It depends on the transport system and protocols. Internet Protocol (IP) video-based cameras can interface directly into an existing network, but can easily saturate the available bandwidth if used at higher resolution than analog cameras. If the update rate is lowered to reduce the bandwidth requirements the video updates so slowly that important details easily can be missed. But a historically short-range technology, FireWire, is being used in a new way to solve many of these problems and reduce costs at the same time. Originally used for video peripherals, external mass storage and the like for PCs and Mats, the Institute of Electrical and Electronics Engineers standard number 1394-2008 (Apple's FireWire) implementation now is being widely implemented in industrial applications. …
